[php] variables

[taekwondokid42]

I want to have a variable with a name that consists of a variable.

My first varible is $war_type.

My second variable is $[$war_type]_cost.


How could I make it so that the engine recognizes $$war_type_cost, but at the same time, recognizes that $war_type is separate from $_cost?

Sorry if this is confusing; I couldn't think of a better way to phrase the problem.

You need to use curly braces and concat the variable to the string. Like this:

$war_type = 'x';
${$war_type . '_cost'} = 10;
//Now you have the variable $x_cost

$war_type = 'x';
${$war_type . '_cost'} = 10;
//Now you have the variable $x_cost

If $war_type is based on user input, make sure it consists of legal characters ([a-zA-Z_]) or you might end up with php errors.
